Have to agree... went into Frankfurt to meet a friend for dinner and coming back, it was difficult to catch the train as there werent that many at night and you had to contend dealing with the S vs. U tracks and that was a little confusing. I got in at 9am and was able to check in, had breakfast in the lounge, they have an egg/omlett station, very nice overall experience.
